Magento 2 website with other hosted (e.g. shopify cart)

Hi,

So I run a couple of small websites (about 400K revenue p.a total.) on Magento 2 open source. I know we’re not in the typical target market for Magento , but overall I’m happy with it, despite the learning curve. We’ve been using Magento for about 7 years. If starting from scratch, we’d probably use something else, but here we are.

On a performance level, we’re happy. We use Nexcess for hosting who we’re happy with. We’re also looking to add a B2B version of one of our sites as we sell wholesale also, which it looks like Magento 2 is a good option for.

My concern is with security and particularly the cart/ payment system. We’ve never had any issues, or security breach on the cart that we’re aware of. BUT, as we’re growing (slowly), I would prefer that the cart security etc.. is handled by someone else, in case of e.g. customer details being stolen from our checkout process.

I’m wondering if it’s possible to have the cart process outsourced to an SaaS type service (e.g. like shopify), while keeping most of the website frontend and backend on Magento?

Also, just wondering if people think Magento will ever offer a SaaS type service for smaller businesses (Enterprise is just way outside our budget). I recall them doing MagentoGo, but seems to be long gone.

Thanks
